The Increased of Photovoltaic Dye-Sensitized Solar Cell (DSSC) Efficiency using Nanocomposite ZnO/TiO_2 with Natural Dye Leaves of Grass Jelly (Cyclea barbata)

摘要

Zinc Oxide (ZnO) is a semiconductor material that is used in addition to Titanium Dioxide (TiO_2) used in the manufacture of Dye-Sensitized Solar Cell (DSSC). ZnO synthesized by using sol-gel mixture of zinc nitrate tetrahydrate (Zn (NO_3)_2.4H_2O), ammonium hydroxide (NH_4OH) and polyethylene glycol (PEG). In this study, the dye was extracted from the leaves of grass jelly (Cyclea barbata). Nanocomposite ZnO/TiO_2 (mixture between ZnO and TiO_2) was obtained by adding the results of the synthesis of ZnO and TiO_2. From fabrication deposited one layer on the FTO glass with a spacious work area 1cm × 1cm obtained increase in conversion efficiency (η) on nanocomposite ZnO/TiO_2 compared with ZnO and TiO_2, with efficiency (η) TiO_2 0.0130%, ZnO 0.0011% and nanocomposite ZnO/TiO_2 0.0696%.
